Description

Die Erfindung betrifft eine Antennenbuchsenhalterung, über die eine Verbindung zwischen in einer HF-Kammer angeordneten elektronischen Bauelementen und außerhalb der Kammer angeordneten weiteren Elementen, beispielsweise einer Antenne, realisiert wird.The invention relates to an antenna socket holder, via which a connection between electronic components arranged in an HF chamber and further elements arranged outside the chamber, for example an antenna, is realized.

Es ist bekannt, daß insbesondere in der Funktechnik die über eine Antenne empfangenen Signale auf elektronische Bauelemente , beispielsweise Schwingkreise, weitergeleitet werden und diese der Signalverarbeitung dienenden Elemente vor jeder weiteren äußeren Beeinflussung durch hochfrequente elektromagnetische Wellen geschützt werden müssen.It is known that, in particular in radio technology, the signals received via an antenna are passed on to electronic components, for example resonant circuits, and these elements used for signal processing have to be protected from any further external influences by high-frequency electromagnetic waves.

Dazu sind diese Bauelemente in HF-dichte Gehäuse, den sogenannten HF-Kammern, angeordnet. Die Verbindung zwischen Antenne und der Schaltung in der Kammer erfolgt über eine Antennenbuchse, die einerseits mit den signalverarbeitenden bzw.-bereitstellenden Bauelementen vebunden ist und andererseits den Anschluß einer Antenne ermöglicht. Verwendung finden hierbei üblicherweise Koaxialbuchsen, die in in der HF-Kammer vorgesehenen Durchgangsbohrungen eingepaßt und angeschraubt und anschließend an den HF-Anschluß angelötet bzw. angesteckt werden.For this purpose, these components are arranged in RF-tight housings, the so-called RF chambers. The connection between the antenna and the circuit in the chamber takes place via an antenna socket, which is connected on the one hand to the signal processing or providing components and on the other hand enables the connection of an antenna. Coaxial sockets are usually used here, which are fitted and screwed into through holes provided in the HF chamber and then soldered or plugged onto the HF connection.

Diese Lösung ist insbesondere nachteilig, weil neben dem hohen Montageaufwand die mit einer Schraubmontage verbundenen Schwierigkeiten in Kauf genommen werden müssen und eine absolute HF-Dichtung nicht erreicht wird.This solution is particularly disadvantageous because, in addition to the high installation effort, the difficulties associated with screw mounting have to be accepted and an absolute HF seal is not achieved.

Der Erfindung liegt die Aufgabe zugrunde, eine Antennenbuchsenhalterung der gattungsgemäßen Art zu schaffen, die eine einfache Montage und verbesserte HF-Dichtung ermöglicht.The invention has for its object to provide an antenna socket holder of the generic type that allows easy assembly and improved RF seal.

Erfindungsgemäß wird die Aufgabe durch den kennzeichnenden Teil des Hauptanspruches gelöst.
Es wurde gefunden, daß wenn die HF-Kammer aus zwei zueinander passenden Gehäuseteilen besteht, in die Gehäusewandung, im Bereich der Trennebene, derart Aussparungen vorgesehen sein können, die einen fest fixierten Sitz einer Koaxialbuchse gewährleisten und die zusätzlich den Einsatz einer wirkungsvollen HF-Dichtung zulassen.
Die weitere Ausgestaltung der Erfindung ergibt sich aus den Unteransprüchen.According to the invention the object is solved by the characterizing part of the main claim.
It has been found that if the HF chamber consists of two matching housing parts, recesses can be provided in the housing wall in the area of the parting plane, which ensure a firmly fixed fit of a coaxial socket and which additionally use an effective HF seal allow.
The further embodiment of the invention results from the subclaims.

Die erfindungsgemäße Lösung bietet den Vorteil der Einsparung von Werkzeug- und Montagekosten durch den Einsatz vorgefertigter Spritzgußteile und den Wegfall einer nachträglichen spanenden Bearbeitung zur Erstellung der Durchgangsbohrung. Ein weiterer Vorteil besteht darin, daß die Verbindung, zum Beispiel durch Anlöten, zwischen der Koaxialbuchse und der Leiterplatte bereits vor der Endmontage erfolgen kann, da diese in einfacher Art und Weise in das Gehäuseunterteil eingelegt werden können.The solution according to the invention offers the advantage of saving tool and assembly costs through the use of prefabricated injection molded parts and the omission of subsequent machining to create the through hole. Another advantage is that the connection, for example by soldering, between the coaxial socket and the printed circuit board can take place before the final assembly, since these can be inserted into the lower housing part in a simple manner.

Die Erfindung soll nachfolgend in einem Ausführungsbeispiel anhand der zugehörigen Zeichnung, die schematisch im Seitenschnitt die erfindungsgemäße Anordnung zeigt, näher erläutert werden.
In der Figur ist gezeigt, daß die HF-Kammer 1 aus einem Gehäuseunterteil 2 und einem Gehäuseoberteil 3 besteht. Die Trennebene 4 zwischen dem Gehäuseunterteil 2 und dem Gehäuseoberteil 3 verläuft direkt achsparallel mit der Längsachse 5 einer Koaxialbuchse 6.
Im Durchgangsbereich der Koaxialbuchse 6 weist das Gehäuseoberteil 3 eine Aussparung 7 und zwei zapfenähnliche Vorsprünge 8, die eine Aussparung 9 bilden, auf. Die Länge der Vorsprünge 8 und somit die Tiefe der Aussparung 9 richtet sich nach dem Durchmesser der Koaxialbuchse 6 und beträgt etwas mehr als der halbe Durchmesser, so daß sich zwischen dem Außenumfang 10 der Koaxialbuchse 6 und der Fläche 11 des Gehäuseoberteils 3 ein Zwischenraum 12 ergibt. Das Gehäuseunterteil 2 weist ebenfalls im Durchgangsbereich der Koaxialbuchse 6 eine Aussparung 13 und weiterhin einen nasenförmigen Vorsprung 14 auf, der mit der durch die Vorsprünge 8 gebildeten Öffnung korrespondiert. Der Vorsprung 14 ist ebenfalls höher als der halbe Durchmesser der Koaxialbuchse 6, so daß sich auch hier ein mit dem Zwischenraum 12 übereinstimmender Zwischenraum ergibt. In diesem Zwischenraum 12 wird die abschirmende HF-Dichtung 15, z.B. in Form von Querrillen, vorgesehen.
Die Aussparungen 7 und 13 bilden eine Aufnahme für einen an der Koaxialbuchse 6 vorgesehenen Flansch 16, der zur lagegenauen Fixierung und Drehsicherung der Koaxialbuchse 6 dient.The invention will be explained in more detail in an exemplary embodiment with reference to the accompanying drawing, which schematically shows the arrangement according to the invention in a side section.
The figure shows that the HF chamber 1 consists of a lower housing part 2 and an upper housing part 3. The parting plane 4 between the lower housing part 2 and the upper housing part 3 runs directly axially parallel with the longitudinal axis 5 of a coaxial socket 6.
In the passage area of the coaxial socket 6, the upper housing part 3 has a recess 7 and two pin-like projections 8, which form a recess 9. The length of the projections 8 and thus the depth of the recess 9 depends on the diameter of the coaxial socket 6 and is slightly more than half the diameter, so that there is a space 12 between the outer circumference 10 of the coaxial socket 6 and the surface 11 of the upper housing part 3 . The lower housing part 2 likewise has a cutout 13 in the passage area of the coaxial bushing 6 and furthermore a nose-shaped projection 14 which corresponds to the opening formed by the projections 8. The projection 14 is also higher than half the diameter of the coaxial bushing 6, so that here too there is an intermediate space which corresponds to the intermediate space 12. The shielding HF seal 15, for example in the form of transverse grooves, is provided in this intermediate space 12.
The recesses 7 and 13 form a receptacle for a flange 16 provided on the coaxial socket 6, which is used for the precise location and rotation of the coaxial socket 6.

Die Montage erfolgt in der einfachen Art und Weise, daß die vormontierte Leiterplatte 17 mit der daran bereits befestigten Koaxialbuchse 6 in das Gehäuseunterteil 2 paßgenau eingelegt wird und durch Aufsetzen des Gehäuseoberteiles 3 eine Arretierung erfolgt. Die Gehäuseteile 2 und 3 können durch geeignete Verbindungselemente, z.B. Schrauben, Spannringe, Schnappverschlüsse oder dergleichen verbunden werden.The assembly is carried out in a simple manner that the preassembled printed circuit board 17 with the coaxial socket 6 already attached to it is inserted into the lower housing part 2 with an exact fit, and a locking takes place by fitting the upper housing part 3. The housing parts 2 and 3 can be connected by suitable connecting elements, e.g. Screws, tension rings, snap locks or the like can be connected.
